1966 Buick Skylark Engine Bellhousing bolt pattern?

Does anyone have a picture or diagram of the bell housing bolt pattern for the automatic trans that bolts to a 1966 Buick Skylark 225 odd fire V-6 engine? Does anyone know what that transmission model number is? Also, does anyone know if the 2004R trans will bolt to this engine? If yes, what year and model vehicle is it from? Thank you very much for your support, Tommy.

 

yeah it should i pretty sure the 225 uses the standard bop pattern the nailhead is the only oddball

 

Right, the 225 used the standard BOP pattern. Same as the 300, 340, 350, 400, 430, and 455. 4 speed auto should be a bolt-on. Others here have done it, maybe they'll post soon...
